Facilitating quality of service flow remapping utilizing a service data adaptation protocol layer

A scheduled entity within a wireless communication network, comprising:

• a processor;
• a transceiver communicatively coupled to the processor;
• a memory communicatively coupled to the processor, wherein the processor is configured to:
• detect a mapping reconfiguration of a first Quality of Service (QoS) flow from a first data radio bearer (DRB) to a second DRB;
• generate a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) in response to the mapping reconfiguration, wherein the SDAP control PDU provides an indication that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB;
• and
• transmit the SDAP control PDU via the first DRB to a scheduling entity via the transceiver.

A method of wireless communication, comprising:

• receiving a plurality of Service Data Adaptation Protocol (SDAP) data protocol data units (PDUs) associated with a first QoS flow via both a first data radio bearer (DRB) and a second DRB from a transmitter;
• receiving an SDAP control PDU applicable to the first QoS flow via the first DRB from the transmitter;
• and
• forwarding the plurality of SDAP data PDU received via the second DRB to an upper layer in response to receiving the SDAP control PDU applicable to the first QoS flow via the first DRB;
• wherein the SDAP control PDU provides an indication that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB.

A method of wireless communication, comprising:

• detecting a mapping reconfiguration of a first Quality of Service (QoS) flow from a first data radio bearer (DRB) to a second DRB;
• setting an end marker parameter in a Service Data Adaptation Protocol (SDAP) header of a first SDAP data protocol data unit (PDU) received from an upper layer after the mapping reconfiguration, wherein the end marker parameter provides an indication that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow on the first DRB;
• and
• transmitting the first SDAP data PDU and at least one subsequent SDAP data PDU associated with the first QoS flow to a receiver, the first SDAP data PDU transmitted via the first DRB and the at least one subsequent SDAP data PDU transmitted via the second DRB.
